as far as i know, MCW is not supposed to be run in the CW portion of the band, from what ive read recently.
One more question:
I have another radio, an elcheapo 1/Beta CB(never even heard of em before) 23 chan w/ crystals, AM only. Im thinking about using this as a transmitter (recrystalled...
Ive also got a practice oscillator id like to use while keying , would it be ok to run the 9v from the oscillator across the ptt switch lines from the mic hookup, that is; to key the radio with a key that has 9v running accross it from a battery? Or should I just power the Osc. from the same...
I figured i would have to manually switch between AM and SSB to rx anything, I can hear CW signals just fine on SSB.
So there wouldnt be any harm done keying the rig that fast/much? And I could just hook my key up to the ptt switch and start keying away in am mode?
I was wondering, if there was any way I could mod my 148 GTL (PC-412 board) so I could xmit some CW on it.
Ive got the extra channel mod on it, and that gives me the very bottom of the 10 meter ham band (where CW is done) and Ive also got my ticket, so Im legal to transmit there.
Ive picked up...
ok... update time:
when I turn on the radio its in "10 meter mode" (mind you, it was never converted to go up into 10 meter, this is just what I call it because its up in those frequencies) and channels above 30 are very quiet (i was able to hear some CW on channel 12, which was 28.035MHz...
... ... yeah... found it... the giant one that says uniden on it... i dont feel dumb at all! its not like i didnt look at it a million times or anything like that. I dunno, it didnt look like an ic to me! more like a giant resistor pack or something. :drool:
one question bothers me still about...
ohh my lord... i dont know if im stupid, blind or what. For the life of me i cannot find IC 2 on my unit, or the Top or Bottom PCB view in the service manual. I can find it perfectly fine on the schem. but just cant see to find it ANYWHERE ELSE!!! someone, please let me know what parts it is...
Good idea, i think ill do that.
Ive already spent hours arm deep in the thing (havent changed much besides the burnt resistors and the voltage regulator, and took off the freebanding channel switches. But I have spent quite alot of time poking and prodding and getting to know the specifics) so...
As far as returning it goes, the seller said they wouldnt accept returns. Plus i'd really like to get it up and running, i think its a nice radio.
The radio is from 89, and i would like to redo all the caps too, im just trying to get a lead on the out of frequency operation.
Im having a...
the VCO voltages are pretty far off if i remember correctly. ill go check them in a little while and post them.
Also, when i say "tap" i mean "tiny slight light touch" It doesnt seem like loose parts, pressure doesnt seem to make any kind of difference when i press the area.
Thanks
... ohhh, what can i say, besides DONT TRUST EBAY!
I bought a "works great" 148 gtl and it turns out it doesnt work so great.
To begin with, when I hooked it up mobile the rx audio would be low until I gave the car some gas. Ive had 2 other mobile units that work fine, so I knew it wasnt the...
